Digital clock realization device and digital clock realization method

Abstract

The embodiment of the invention provides a digital clock realization device and a digital clock realization method. the digital clock realization device comprises an oscillator, a processor and a display, wherein the oscillator is used for generating clock signals and outputting the clock signals to the processor; the processor is used for carrying out counting according to the clock signals, generating time information and outputting the time information to the display; and the display is used for carrying out time display according to the time information. The clock signals generated by the oscillator serve as the working time sequence of the processor and the time information source, the time information is thus determined, and finally, the time information is displayed through the display. Through the embodiment of the invention, influences on time sequence signals due to adoption of multiple separate TTL digital circuits and temperature drift can be avoided, and the timing accuracy is thus improved.

Description

technical field [0001] The invention relates to the technical field of timing, in particular to a digital clock realization device and a digital clock realization method. Background technique [0002] Digital clock is a device that uses digital circuit technology to realize hour, minute and second timing. Compared with mechanical clocks, it has higher accuracy, intuitiveness and service life, and has been widely used. There are many ways to design a digital clock, for example: use a dedicated electronic clock chip with a display circuit and the peripheral circuits it needs to form a digital clock. [0003] Specifically, the traditional solution uses a 555 timer to generate a clock signal, and then divides the frequency by multiple counters in series (for example: a preset decade synchronous counter) to generate a 1Hz clock signal, and then the 1Hz The clock signal is input into the cycle counting circuit, and finally, the time counting result is displayed, and finally the t...

Problems solved by technology

[0004] In the above technical solution, multiple TTL digital circuits (transistor-transistor logic circuits) are used, the timing signals between these separate TTL digital circuits will be delayed, and these TTL digital circuits will also be affected by temperature, these delays Time and temperature effects will lead to inaccurate counting accuracy, resulting in poor timing accuracy
